Quality Control

Our 1,3-Dioxolan-2-One,4,5-Dichloro-,trans-(9Ci) is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure high chemical purity, isomeric integrity, and consistency. Standard quality parameters include assay (HPLC), identification (IR, NMR), and control of key impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be kept in the original packaging or amber glass until use to prevent degradation.
